The UBL technical committee only standardizes the document models 
used for information interchange, it does not mandate any business 
process or conventions of use of the available document models to 
meet anyone's particular requirements.

Communities of users will standardize business processes and 
conventions of using UBL documents for different business 
requirements.  OIOUBL, NES and CCI-UBL are all examples of how 
communities of users have published their expectations of the use of 
standardized UBL document models.

You are welcome to use UBL documents in any fashion you wish ... the 
only normative aspect of the UBL 2.0 specification is that you use 
XML documents and that those documents validate against the normative 
XSD document models.

Note that there are communities of users creating document models 
that are compatible at the model level with UBL in that their 
business objects are derived from UBL business objects.  But at the 
document interchange level those documents would not be considered 
conformant, only compatible.  In our preliminary discussions of UBL 
Conformance we are basing this distinction by describing UBL 
Compatibility at the model level and UBL Conformance at the document level.

This is all being spelled out in committee documents and the editors 
are underway with drafts for committee review.

I hope this helps.
